You need to run on your toes if you want to proceed down this road. If you can't run on your toes, well then you're out of luck, and you won't be able to move on at all. I didn't make this rule, I just enforce it. Now run!

If you find that you can't proceed, you're a fool (ふ). Everyone can run on their toes. Don't you know that? No? Then you're an even bigger fool, now get outta here!
